EXTENSION TABLE Applicationfiled June21, 1932. Serial No. 618,433.

This invention relates to extension tables. The main object of the invention is to provide an'improved extension table the top of which may be extended in either one or two directions as desired. 1 Some features of the invention may, however, be embodied in a table which is extensible in only one direction.

Tables constructed so that they maybe extended in one direction are well known, a familiar example of such tables being the usual dining table constructed so that the two ends may be drawn apart to leave a space between the two parts of the table top for the insertion of extra leaves.

A table embodying all the features of the present invention has a main table top and endand side extension top sections or leaves, and a supporting frame 'or body Wh1Ch'1S most desirably rectangular and of nearly the same length and breadth as the table top, the connecting means between the main table top and the supporting body being such that the main table top may rest in normal 5 position in which it alone serves to form the top of the table, or may be connected tot-he supporting body ina position offset from its normal position in one direction to permit one of the extension leaves'tobe positioned on the support to extend the top in the opposite direction, or may be connected to the supporting body in. a position offset diagonally from its normal position v to permit both of the extension leaves to be positioned on the support to provide a table top which is extended in two transverse directions, that is, both lengthwise and crosswise of the table.

An approved embodiment of the invention is shown by wayof example in the accompanying drawings, in which Fig. 1 is a perspective view of-the table, showing the main part of the table top in diagonally offset position preparatory to placing the end and side extension top sections in position Fig. 2 is a plan view of the supporting body or frame; 7 3'is a sect-ion on the line 3-3 of Fig. 2, with the'main top section in position;

Fig. 4: is a section on the line H of Fig. 3;

Fig. 5 is a top plan view of the table with only the main section of the table top in position; 1

Fig. 6 is a top plan view of the table with the end extension top section in position;

Fig. 7 is a top plan view of the table with both end and side extension top sections in position;

Fig. 8 is a section on the line 8-8 of Fig. 7;

Fig. 9 is a section on the line 99 of Fig.7; and 5' Fig. 10 is a vertical section through one of the headed projections on the table top sections and its cooperating slot.

The table comprises a table top supporting frame or body generally designated as 10, supported by apair of pedestal type legs 11. The table top comprises a main top section 15, an end extension top section or leaf 16 and a side extension top section or leaf 17 The supporting body comprises an upper frame 21 which serves as theimmediate support for the main top section and also for the extension leaves when in use. Below this frame 21 (see Figs. 3 and 4) the body 'is formed to provide a shallow storage compartment 22, having a hinged door 23 at one end to receive the end section or leaf 16 when not in use, and a shallow compartment 24 beneath the compartment 22 and having a lriZnged end door 25 tohold the side section 1 i For securing the main table top 15 to. the supporting frame 21 and for permitting it to be shifted from its normal position in whichv it serves as the complete top 'of the table as indicated at Fig.5 to an endwiseolfset posidinally of the frame and having two spaced 9 parallel undercut slots'31 and 32 extending transversely therefrom, and the table top 15 is provided with two shouldered or headed studs 33, of which one is shown in Fig. 10, ex-

tending from the under side thereof and 1 spaced apart longitudinally of the top a distance corresponding to the distance between the transverse slots 31 and 32. The underout slots 30, 31 and 32 are provided by means of a slotted metal plate 34 having two laterally extending slotted arms 35 and 36, this plate and its arms being set into the upper surface of parts of the frame 21 over channels cut in the frame parts as shown in Fig. 10. The slot 31 extends from one end of the longitudinal slot 30 near one end of the table, and the slot 32 extends from the slot 30 at a point near the middle of the length of the frame 21, and from this point the slot 30 extends on for a suitable distance toward the other end of the frame 21, ending at such a point as not to interfere with the placing of the end extension leaf-16. The holding studs 33 on-the under side of the table top are positioned so that when one of the studs is in the right hand end oftheslot 30, as viewed in Fig. 2, the top 15 will be in its normal position shown by Fig. 5, and when the top is moved lengthwise to bring the other stud to the other end of the slot 30, the top 15 will be in the longitudinally offset posltion shown by Fig. 6. Vhen in this position the two studs willbe opposite the ends of the two transverse slots 31 and 32, so that the top 15' may then be moved transversely to the diagonally offset position shown by Fig. 7-, in which position the studs 33 will be at the outer. ends of the slots 31 and 32 and the top 15 will then have been shifted diagonally from its normal position. In order to permit the holding studs .33 to be entered into the slot 3. the slot isformed with two suitably spa-red enlargements 37. V V

Instead ofrelying entirely on the engagement of the holding studs with theends of the slot to limit the longitudinal movementof the table top 15, a stop cleat 38 is desirably secured to thevunder side of the table top in position to engage the end cross piece 39 of the frame 21 when the table top is in its normal position and to engage a cross piece 40 of the frame 21 when the table top has been movedto the position shown by Fig. 6.. A recess 11 is formed in the frame to receive the stop cleat 38 when the table top 15 is moved transversely to the position shown by Fig. 7.

When it is desired to lengthen the table without increasing its width, the main top 15, is moved longitudinally to the offset position shown in Fig. 6 in which it extends beyond oneend of the supporting frame 21 and a portion of the supporting frame at the other end is left uncovered. The'end leaf 16 is then placed on-the uncovered end portion of the supporting frame with its inner edge abutting against the endedge of the main top 15. The width of the leaf 16,, or

its dimension widthwise of the table when positioned on the supporting frame, is equal length longitudinally of the table is such that when positioned on the uncovered end portion of the supporting frame abutting against the end of the main top 15 it will project beyond the end of the supporting frame a distance equal to the distance which the other end of the main top 15 projects beyond the supporting frame when in its longitudinally offset position. In order that the leaf may when not in use be stored in the compartment22, it is made in two parts hinged together on the line 15 of Figs. 6 and 7 and as shown at 46 in Fig. 4 so that the two parts may be folded together. For securing the leaf 16 on the supporting frame, the edge ofthe leaf which abuts against the end edge of the main top 15 is formed to interlock with such edge of the main top and the under side of the leaf isprovided with a pair of shouldered or headed studs similar to the studs 33 of the main top adaptedto be entered into holding engagement in a corresponding pair of undercut slots 47 suitably positioned in a part of the supporting frame. These slots likethe slots 30, 31 and 32 are provided by means of slotted metal plates set into the upper surface of a part of the supporting frame over cut away portions thereof, each slot being of right angled form, one arm extending longitudinally of the frame and having an enlarged portion at its outer end for entrance of the shouldered stud and the other arm extending from the inner end of the slot transversely thereof.

The edges of the main top 15 are formed as shown in the drawings with a projecting beada, and the inner or abutting edge of the end leaf 16 is complementarily grooved, as best shown at b in Fig. 9. In placing the leaf 16 on the uncovered end portion of the supporting frame its holding studs are first entered through the enlarged ends of the slot-s47 and the leaf is then slid inward to bring its inner edge into interlocking engagement with the end edge of the table top 15 and is then slid sidewise to move its holding studs .into the transverse portions of the slotsi'i, The leaf will then be held releasably in the position shown in Fig. 6, form-H ing with the main top 15 a longitudinally extended top for the table.

When it is desired to widen the table top as well as to lengthen it, the main top 15 is moved into the position shown by Fig. 7, thus leaving one side portion as well as one end portion of the supporting frame uncovered. The end leaf 16 is then positioned as before but with its holding studs entered into a second pair of undercut slots 48 provided in a part of the supporting frame and spaced laterally from the slots 47 a distanceequal to the transverse movement of the main top w 15. The side leaf 17 is then positioned on the,

uncovered side portion of the supporting frame with its inner edge abutting against 10 are placed end to end (see Fig. 8). The edge of the side leaf 17 which abuts against the side edges of the main top 15 and leaf 16 is grooved to interlock with the edges of the main top and end leaf. and the leaf 17 is 5 secured in position on the supporting frame by holding studs similar to the studs 33 of the main top on the under side of the leaf entering right-angled undercut slots pro vided in parts of the supporting frame.

20 There are in the construction shown three pairs of these slots 51, 52 and 53 respectively. The slots are formed in metal plates set in the upper surface of the frame parts and each has an enlarged outer end to permit entrance of the corresponding holding stud, each slot extending first inwardly crosswise of the table and having a transverse inner end portion. One of the parts, 17a, of the 40 be positioned with its end edges in line with the outer ends of the main top 15 and end leaf 16 and with its inner side edge in interlocking engagement with the abutting edges of the main top and end leaf.

The main top 15 has both side edges and both end edges finished with a projecting beading a. The end leaf 16 has the same beading a on its two side edges and on one end edge with the other end edge complementarily grooved; and the two parts of the side leaf have the same projecting beading on one side edge and on one end edge and have the other side edge complementarily grooved. The top of the table will thus have the same edge finish all around whether it is formed by the main top 15 alone or by the main top and the end leaf or by the main top and both the end and the side leaves, and the abutting edges of the main top and the end leaf, and of the main top and end leaf and the side leaf, will have chmplementarily formed interlocking edges which aid in holding the end and side leaves in position on the supporting frame and in providing a rigid tabletop of either of the three possible sizes.

To permit the twov parts of the end leaf 16 to fold fiat together as shown in Fig. 4, the part which is not provided with the holding studs has suitable recesses therein (not shown) to receive the holding studs on the other part. Similarly, to permitthe two parts 17a and .17 b of the side leaf 17 to lie fiatwis'e together with their under surfaces incontact as shown in Figs. 3 and 4:, the under-sides. of each part are recessed to receive the holding studs of the other part. Any suitable means may be provided for holdin the hinged doors 23 and 25 at the ends 0 the storage compartments 22 and 24 closed and for permitting them to be opened when desired..."
